Draw spikes are one things, continuous current is another. How long is that spike? 1/100 second? 1/1000 s? You need to quantify it somehow.

I challenge you to show us a data log from those cars that allegedly dumped a pack in 3 minutes.
For a pack perhaps not, as the wiring and connectors are frequently the weak part of the chain. But here is a 2.2Ah cell being tested at up to 50C continuous, 110 amps, for a full discharge, by a well known independent tester. Better cell capability provides better performance, higher voltage under load, even when the current is much much lower.

C rating is a very common and very useful rating method for batteries overall, has been for a long time and will continue to be. Relatively new to RC is all.
